OSX with ExFat exterior drive not absolutely accessible from Home windows shoppers

Because the title says, I’ve an outdated Mac working 10.13 (Excessive Sierra) with an 16TB exterior drive formatted to ExFat that serves as my important “backup” drive for each pc in my house.

Some background: I used to have a 5TB drive (formatted as HFS+) for this and the whole lot (i.e. all of the situations listed beneath that are not engaged on the brand new drive) labored flawlessly. However house was working low so I wished to improve to a more moderen one. Provided that my Mac can also be fairly outdated, I wished the brand new drive formatted in ExFat so when the Mac dies I may then, and solely then, swap it to a more moderen PC.

The problems: On the Mac, I can copy the information to the brand new drive utilizing Past Examine and my cloud backup service appears to don’t have any drawback seeing the brand new information and even thinks they match with the prevailing backup set so it would not attempt to add them once more. That is nice.
However on all my Home windows machines that join it, issues began to not work with the brand new drive. Chrome cannot save downloads to it and offers a very unspecified error. I can not manually add information to the drive. For instance I hook up with the drive and open up an current folder. I can see information in there. But when I right-click and select New -> Wealthy Textual content Doc, Home windows instantly says “Unable to create file ‘foo’. There may be not sufficient house on the disk.” Winamp can now not scan the folders on the brand new drive (I can not discover any errors). There are different oddities however these are the principle ones for me. Like I mentioned above, all of those situations work high quality when connecting to the older HFS+ drive from my Home windows machines however not the brand new ExFat drive. And I can do the whole lot on the Mac with no points (at the very least with Chrome downloads and creating information). I’ve tried connecting to the drive through and making an attempt to share particular person folders on the drive. Identical outcomes. It seems to be to be how the Mac is opening connections to Home windows however I do not know what the repair is, if any.

Any concepts right here can be appreciated. However I am eager on preserving the backup drive on the Mac so long as that machine is working.
